Warnings and Alarms
ALARM 31, Motor phase V missing
Motor phase V between the adjustable frequency drive
and the motor is missing.
Remove power from the adjustable frequency drive and
check motor phase V.
ALARM 32, Motor phase W missing
Motor phase W between the adjustable frequency drive
and the motor is missing.
Remove power from the adjustable frequency drive and
check motor phase W.
ALARM 33, Inrush fault
Too many power-ups have occurred within a short time
period. Let the unit cool to operating temperature.
WARNING/ALARM 34, Fieldbus communication fault
The serial communication bus on the communication
option card is not working.
WARNING/ALARM 36, Mains Failure
This warning/alarm is only active if the supply voltage to
the adjustable frequency drive is lost and 14-10 Mains
Failure is NOT set to [0] No Function. Check the fuses to the
8 8
adjustable frequency drive and line power supply to the
unit.
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
the table below is displayed.
Troubleshooting
